Reflection of electromagnetic waves at the corrugated boundary between permeable dielectrics
The reflectivity of periodically corrugated boundaries between non-lossy, isotropic dielectrics with different magnetic permeabilities is studied in a regime where the grating supports only a specularly reflected order. The propagation direction of the incident plane wave may form arbitrary angles w...
